Film capacitors, also known as Plastic Film Capacitors, are non-polar capacitors that are designed and manufactured for medium voltage, high frequency (DC or AC) applications. Film capacitors, including SFT37S50-5K391E-F capacitors, are known for their robustness, accurate tolerances, stability over temperature, and low temperatures coefficient of capacitance (TCC).

The SFT37S50-5K391E-F Capacity is a metallized film capacitor. It is a vertical structure capacitor featuring high capacitance, high reliability, and extremely low equivalent series resistance (ESR). The capacitance ranges from 1uF to 4700uF. The construction of the SFT37S50-5K391E-F is a combination of metallized film and winding-type film form, giving the capacitor high current loading capability. The maximum operating voltage (Vmax) is 5KV.

The application fields of SFT37S50-5K391E-F are mainly in power supplies, power amplifiers, communication circuits, automotive electronics, industrial equipment, lighting and sound protection, transistors, and HID (High Intensity Discharge) lamps. The capacitors can be used in a wide range of applications, such as high-frequency decoupling, pulse filters, rail switching power supplies, electrolysis power supplies, automotive inverter circuits, DC stabilizing circuits, and snubber circuits.

The working principle of SFT37S50-5K391E-F capacitors is based on the principle of dielectric absorption and the Faraday\'s law of induction. The dielectric material of the capacitor absorbs the electric field generated across the capacitor plates and stores the electric energy. This absorbed electric energy is then released when the voltage across the capacitor plates is changed. The amount of energy stored in the capacitor is proportional to the capacitance value of the capacitor. The Faraday\'s law of induction states that the induced current in the circuit is directly proportional to the rate of change of flux.

The SFT37S50-5K391E-F capacitors are designed to provide maximum stability over temperature and low TCC. The low TCC ensures a stable output even under extreme temperature conditions. The high capacitance and high reliability make the SFT37S50-5K391E-F capacitors suitable for applications which require long-term operation. The extremely low ESR ensures a reliable connection even under high frequency and high voltage. The SFT37S50-5K391E-F capacitors have a wide range of uses in many industries.
